Improvement in apparatus for distilling



UNITED STATES FFICE PATENT H. A. SOHESGH, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN APPARATUS FOR DISTILLING.

T0 all whom z't mag; concern:

Be it known (hat I, H. AUGUST SGI-IESGH, 0f the city ofBx-ooklyn, E. 1)., county ofKings, and Stare 0f New York, bave invented a new and Improved Distilling Apparatus; and I d0 hereby declare tl1at tl1e following is a full, clear, and exact description of the same, enabling others skilled in tl1e an. t0 make and use the same, referenee being had to the accompan ying drawings, forming part of this speeification, in Wliich Figure l represents a vertieal central section 0t' this invention, the line x x, Fig. 2, indicating tl1e plane of section. Fig. 2 is a horizontal seetion of the same, taken in the plane indieated by the line y y, Fig. 1.

SimiIar letters of reference indicate c01responding parts.

This invention eonsists in exposing the upper portion OI vapor-space 0f a still for petroleum or other liquids t0 the aetion 0f an additional fire from a secondary fire place built abo.ve the main fire-place, whicli serves t0 l1eat the contents 0f tl1e still in such a manner that all ihe impurities contained in the vapors are precipitated, and the 0il 0r product obtained is whiter 0r purer than that obtained from an ordinary distilling apparatns.

A represents a still 0f wrought-iron, castiron, or any other suitable Material, and 0f an upright oylindrical 01 0f a horizontal or any other suitable forn1 or shape. 'lhis still is set 0ver the fire-plaee B,whiuh i s so situated that a fire built in the same strikes the bottom of the still and heats the contents thereof in the ordinary manuer. From the middle 0f the still projects a flange, a, Wl1lll touches the furnacewall all around, so that the combnstion-chamber D is separated in two compartments,which cornmunicate with each other through openin gs b, that can be closed by means of dampers, as shown in Fig. 2. When tl1ese dampers are el0sed the tire from the fire-place B is eoniined t0 the lower part of the combustion-chamber, which connects, by means 0f a suit able flue, witl1 the chimney 01 smoke-stack O.

The upper part of the combustion-chamber communicates,through apertures c, with the secondary fire-place E, which is built above the maiu fire-place B, as elearly shown in Fig. l 0f the drawings.

When atire is built in the secondary fireplace the products ofcornbustion pass through the apertures einte tl1e upper part 0f the 00mbustion-chamber and heat the upper 01' vapor spaee 0f a still, so that the vapor contained in the same is superheated, and by these means all the impurities mixed with said vapors are caused t0 precipitate; whereas in stills 0f 01"- dinary construetion the vapors are liable t0 carry up sonne impurities und to yiield an impure prodnct. 'lhis defect is particularly 0bjectionable in stills for petroleum, since it is the main cause 0f the coloring 0f the 0il as the same runs from' tl1e still. In my still said defect is entirely avoided, am]. yields a whiter and purer product than any still knowu t0 me.

What I claim as new, and desire to secure by Letters Patent, is l Exposing the upper part or vapor-space 0f a still t0 ehe action of an additional fire built in a secondary fire-plaee, substantially-iu the manner and f0r the purposes sei: forth.
